I think that is an old Audax 3" mid. Not sure if they are even still made.

Pictures of the cabinet would be helpful.

The cabinet is like so....

this is what i pulled off a site:
Bass: 1 x 25 cm

Mids: 1 x Polycone

Highs: 1 x EMIT

Suggested for amplifiers with: 20-135 Watts per channel

Frequency range: 42 Hz - 45 kHz

Crossover frequencies: 500 Hz, 5000 Hz

Thanks poojou, that helps.

For a 10" 3 way there are abundant options. If the old EMITs are still working, it would be fun to match a ribbon midrange. I will rummage through some options.

Woofers have gotten very good in recent years. If you can get me the cabinet dimensions (internal, or external and wall thickness) I can run some simulations on sealed and vented options.

The crossover is always the biggest pain. If you decide to re-driver, you will need to dig them out of there and diagram the circuit. We can figure out what you are working with from there.

Trivia: EMIT was Infinity's acronym for "Electro-Magnetic Induction Tweeter". We always called it a ribbon, but I don't recall whether it is edge driven or surface driven. Anybody know?

The cabinet seems very solid to me, so it is worth to use it, but I agree that three ways speakers is harder to get kits, or anything similar, one thing is sure, I think that PartExpress and Madisound offer a crossover design service if you can tell them the drivers are you going to use, so maybe it is worth to get from them the drivers, in 10" there is a huge variety, you could get a ribbon mid as gerG said. And you will end with a much better speaker, for less than a new one with a more crappy sound

THanks for the opinions guys, i'll try to get cabinet specs for you gerg, i am gonna fix the foam surrounds first, and see how they sound, then, maybe later i'll chuck some decent woofers/midranges in...(no money leh)
